Police are still searching for the gunman who shot and killed opposition parliamentarian Yont Tharo's son and wounded three others Sunday night near Wat Botum following a traffic altercation. Yont Tharo, who filed complaints with the Ministry of Interior and Muncipal Police earlier this week, said he had yet to hear of any new information in the case. Phnom Penh Municipal Police Chief Touch Naruth said on Tuesday that police had identified a suspect and were close to making an arrest.
